[Offer] Palm OS stuff
I have working simulators for the Palm T|X and Z22, as well as the Palm Desktop software that shipped with the Zire 31 as an ISO.
Additionally, I have a few old Palm programs. Dope Wars, FindHack, GreyPaint2, FreeJongg, Pac Man, Strategic Commander, and Tech Sounds. I have a few other pieces of software that I'm not 100% certain on - Universe.PRC which I think is WAP Universe, SCUDATTC (Scud Attack?) and "Keyboard v113". As well, I apparently dumped the Palm Photos app at one point, so I have the PRCs and PDBs for that, too.
I've successfully run the simulators on Windows 10 without any glaring issues, as well as Palm Desktop (although I haven't yet been able to sync it with a handheld)
EDIT: Found a few other things poking around; a bunch of skins for Skin UI (though, no Skin UI executable) as well as a digitizer app and Warfare Incorporated.
